Title: Improvements in or relating to Transformers and the like for use with Compounded Dynamo-electric Machines.
Inventor: HEYLAND ALEXANDER
Filed: 1904-12-08
Granted: 1905-06-01
Abstract: 26,791. Heyland, A. Dec. 8, A.D. 1903, [date applied for under Patents Act, A.D. 1901]. Dynamos, regulating; motors, controlling. - In the compounding - arrangements for alternating- current machines described in Specification No. 25,221, A.D. 1901, the shunt and series currents are supplied to the rotating field magnets through a single transformer. The armature winding of a three-phase machine is represented diagrammatically in Fig. 1<a>, with the three phases I, II, III, and the corresponding ends of the phases o<1> a<1>, o<2> a<2>, and o<3> a<3>. In the transformer shown in Fig. 1, having secondary terminals I, II, III, the ends a<3>, a<1>, a<2> of the shunt winding and the ends o', o<2>, o<3> of the series winding are directly connected with the similarly-named extremities of the armature winding, in such a manner that the shunt and series coils on any one leg of the transformer are always connected to different phases of the armature winding which are displaced 90‹ elatively to one another. The regulating-resistance W is placed in the shunt circuit. The application of the invention to single-phase and two-phase machines in conjunction with threephase transformers is also described, the two phases in the latter case being- linked together on the transformer according to Scott's connections.

Title: Improvements in Revolving Hook Sewing Machines.
Inventor: FAIRWEATHER WALLACE
Filed: 1904-12-22
Granted: 1905-11-16
Abstract: 28,085. Fairweather, W., [Singer Manufacturing Co.]. Dec. 22. Lock-stitch hook sewing- machines ; multiple-needle machines ; governing under thread.-Relates to rotary-hook machines and particularly to that described in Specification No. 15,112, A.D. 1903, the only part of the latter which is modified being the stitch-forming mechanism. The spool case 28, Fig. 6, rests freely in a cup-shaped hook part 25, which is given continuous unidirectional rotation as in the prior Specification. A hook on the cup portion spreads the needle loop round the bobbin case, one limb of the loop passing above and the other below the case. To prevent the spool case from rotating by its frictional engagement with the part 25, a projection 31 on it takes in between two lugs 33, 33<1> which depend from the throat-plate and allow of a little play to the projection 31. Rotation of the hook part sets the projection against the lug 33, and to enable the upper limb of the loop to pass over the top of the case, the latter is pulled by means of its thread 30 in a counter-clockwise sense by an oscillating hook 27. The hook is of the form shown in Fig. 7, and is operated by a cam 25 that engages the yoke 24. The upper limb of the loop is then enabled to jump the other projection 33<1> by the release of the bobbin thread by the hook. This enables the cup part to rotate the spool case frictionally, so that its projection leaves the lug 33<1> and opens a passage for the loop.

Inventor: HALSTEAD HORACE
Filed: 1905-04-20
Granted: 1906-02-22
Abstract: 8443. Halstead, H., Johnson, A., and Winn, S. April 20. Electric tramways on the overhead - conductor system. Collectors.-Consists in supporting the trolly pulley so that, when it leaves the overhead conductor, it automatically becomes free to tilt or fall over upon meeting any obstructions. Fig. 1 shows a side and Fig. 3 a sectional end view of a trolly head. The pulley b is mounted upon a spindle c, passing through the bearing- block d, which is capable of turning on trunnions e in extensions f of the tube a. The block d and extensions fare slotted so that the projections h of the loose collar i, which surrounds the spindle c can move under the action of the spring k and the pressure on the trolly pulley. When the pulley engages the overhead wire, the projections h are forced down into the slots in the extensions f, thus locking the spindle in an upright position. Upon the pulley leaving the wire, the projections rise clear of the outer slots, when the pulley and block d are free to move on the trunnions e after obstructions are passed, the pulley is returned to its upright position by the springs g. The spindle c may be mounted on ball bearings as shown, and the springs and trunnions cased in by caps.

Title: Improvements in Boiler Tube Cleaners.
Inventor: WEINLAND HENRY FORRY
Filed: 1905-04-26
Granted: 1905-06-22
Abstract: 8839. Weinland, H. F. April 26. Cleaning pipes and tubes.-Relates to boiler-tube cleaners of the rotary type having cutters mounted upon centrifugally-acting arms and driven by a turbine&c. Fig. 1 shows the cleaner inside elevation, and Fig. 2 in front elevation, and Fig. 7 is a detail view of the head showing the grooves in which the pivot pins slide. The head A is constructed with an upper and lower plate C united by a web D, leaving recesses E for the cutter arms F. The forward cutters H and the rear cutters I are mounted freely upon bearing-pins G secured in the arms F, and the cutter arms are pivotally mounted at K between the plates C, so as to permit of their sliding radially. The arms are mounted with the pivots placed behind their longitudinal centres of gravity, and the forward ends thus have a greater cutting moment. The cutters can adapt themselves to the amount of incrustation, as the pivotal movement can take place at any part of the sliding movement.

Abstract: 16,283. Symonds, H., Hall, J. C., and Harker, H., [trading as Hall & Co., J. C.]. Aug. 10. Guards ; belt forks, operating.- Relates to guards for laundry machinery and the like of the type described in Specifications Nos. 4290 and 9630, A.D. 1904. Supporting- links are arranged in line with rods connected to the disconnecting - mechanism, and operative weights or springs are arranged to be brought into action when this arrangement is disturbed. The cross-bars Y, Z, Figs.1 and 2, are carried by end plates 8 pivoted at R to the upright T of an ironing-machine. A link X connects them with the rod Q and the hand-lever U, the rod Q being pivoted about the point F of the bracket A through the medium of the lever G. The bracket A is slotted at C and E so that the rod Q and link G may be arranged normally to lie in the same straight line, the link G resting against a stop H in this position. The rod Q is connected to the clutch of the pulley I through the bell-crank levers 0, L and the link K. The link K is slotted at k so that the weight P in falling obtains such an impulse that the clutch is withdrawn with certainty. The rods Q, U are slotted at q, u respectively, so that when, by moving one of the cross-bars, the rod Q is raised sufficiently, it falls the length of the slot q and, through the fall of the weight P, releases the clutch. The hand-lever U serves to return the arrangement to its normal position. For a wringer guard, the pivoted end plates 7 of the cross-bars 5, 6, Figs. 4 and 5, are connected by links 8, 9 with the lever 11. The lever 11 is fulcrumed at 18 to a bracket 10, and its end 12 works up and down in a slot 14 of the guide 13. The guide also engages a pin 15 of the lever 16, pivoted at 19 to the striking-bar 1 of the machine. A movement of the cross-bars raises the ends of the levers 11, 16 so that the belt-fork 4, under the influence of the spring 20, is moved from the fast pulley 2 to the loose pulley 3.

Granted: 1907-07-25
Abstract: 27,113. MÚran, M. Dec. 8, 1905, [date appliedfor under Patents Act, 1901]. Gas and like engines.-The engine described has six cylinders arranged in pairs to drive three cranks set at 120 degrees. The two cylinders of a pair give impulses alternately to the same crank. Regulating speed and power non-automatically.- In a four-stroke-cycle engine, the exhaust valve may remain open during a part of the suction stroke, so that exhaust gases are drawn into the cylinder. During the remainder of the stroke, the admission valve is open ; the engine thus operates with variable admission but with constant compression. The admission-valve cams I, II, III, Fig. 4, and the exhaust-valve cams I, II, III, Fig. 3, are on separate shafts and are complimentary to one another, so that the admission valve opens when the exhaust valve closes, and the whole period from the commencement of exhaust to the end of admission is the same for each pair of profiles I, II, or III. The cams are adjusted by sliding the cam shafts longitudinally. Cylinders; arrangement of charge; preventing mixing of new charge with exhaust; preventing failure of ignition.-To obtain statification, the explosion chamber and the back end of the cylinder form a relatively long passage, the cross-section of which increases progressively in the direction in which fresh gases travel during admission. The sparking-plug is placed close to the admission valve, where the charge is free from exhaust gases. Starting ; stopping ; reversing.-The engine is started by compressed gases admitted to each cylinder during a part or the whole of the power stroke through auxiliary valves h<2>, Fig. 2, which also act as non-return valves for charging a reservoir with combustion products. The valve h<2> is operated from the admission valve-rod e<1> of another cylinder by the levers h, n, rod o, and bell-crank lever r. The latter, meatiog the stop-nut s when the valve-rod e<1> is raised to its highest position, is thrown out of engagement with the rod o, and the valve h<2> closes. If the rod j carrying the fulcrum i of the lever h is slightly raised, the bell-crank lever does not engage the stop, and the admission of compressed gases continues until the end of the stroke. If the fulcrum i is raised to i<1>, the valve h<2> is not lifted. Cam-profiles w, similar to the profiles I, are provided for the reverse motion. The engine is braked and reversal effected by sliding the shafts to bring the cams w into action, and depressing the rod j so that compressed gases are admitted to the cylinders at the correct time for starting in the reverse direction.

Title: Process for Preparing Printing Plates by Means of Electrolytic Etching.
Inventor: STRECKER-AUFERMANN HANS
Filed: 1906-12-12
Granted: 1907-12-12
Abstract: 28,319. Aufermann, H. Strecker-. Dec. 12. Etching.-In an electrolytic etching-process for preparing iron, steel, nickel, zinc, copper, brass, or other metal printing-plates, the plate is provided with a chrome-gelatin, chrome-glue, chrome-gum, chrome-albumen, or like image layer, and is used as an anode, with the face towards a cathode of any kind, in a concentrated solution of a tanning- agent, such as tannic acid, chrome alum, ferrous or ferric chloride, copper sulphate or chloride, chromium chloride, manganese chloride, zinc sulphate or chloride, nickel sulphate, magnesium sulphate, ammonium sulphate or chloride, sodium sulphate, thiosulphate, or chloride, or potassium ferricyanide. The edges of the plate are protected by coating with varnish. A series of plates may be placed in one bath, with the faces anodic and the backs cathodic. The current may be continuous or interrupted. The process may be selfexciting, the plate forming the negative pole of a Daniell's, LeclanchÚ, or other cell. The bath may be gradually diluted, or the dilution may be effected by diffusion between concentrated solution in an anode chamber and dilute solution in a cathode chamber. When a zinc plate is used in ferric-chloride solution, precipitation of iron hydroxide behind the layer is prevented by addition to the solution of a material, such as potassium ferricyanide, oxalic, citric, or tartaric acid, sugar, glycerine, or sodium acetate. The plate is finally cleaned with sodium hydrate &c., and is re-etched as above or in the ordinary manner.

Title: Apparatus for Continous Indication of Sea-soundings.
Inventor: STEVENS SAMUEL HENDY
Filed: 1907-03-27
Granted: 1908-01-23
Abstract: 7291. Stevens, S. H. March 27. Sounding - apparatus. - The movement of the pressure tube of a pressure gauge of the Bourdon type alters the resistance of a coil in circuit with an ammeter and generator on the vessel, and thus the indications of the ammeters are made to vary with and indicate the depth of water at any instant. The pressure tube i is within a chamber b the walls of which are of insulating-material; the chamber is in a case a, to terminals j in which are attached insulated cables k of copper of suitable size for the conditions of working, connected to the ammeters on the ship. These terminals are connected to terminals on the chamber b between which is a resistance coil c. At regular intervals, wires e are attached to the coil c and penetrate the walls of the chamber b to make contact with a flat semicircular coppered steel spring f, one end of which is connected to the chamber and the other to an insulation link g, which is connected by a lever h to the end of the pressure tube. The spring f at ordinary pressure makes contact with all the wires e ; but, as the pressure increases, the motion of the lever h unwraps the spring and introduces, step by step, the resistance coil c, the ammeter reading consequently falling. The resistance of the circuit less the resistance between the terminals d is such that a reading of, say, 3 amperes is obtained. When the resistance coil and spring are included, the reading would be 2À5 amperes, and when the spring is unwrapt, 0À8 amperes, so that the fathom column extends only from 0À8 to 2À5 amperes, and no greater depth of water can be indicated than that experienced, as a breakage would give a zero reading and a short-circuit a reading greater than 3. The ammeters may be provided with means for ringing an alarm bell when the water reaches any predetermined depth. The apparatus is attached to a sinker consisting of two circular plates of metal revolving on an axle placed eccentrically.
